[This test on roachdash](https://roachdash.crdb.dev/?filter=status:open%20t:.*TestConcurrentZip.*&sort=title+created&display=lastcommented+project) | [Improve this report!](https://github.com/cockroachdb/cockroach/tree/master/pkg/cmd/bazci/githubpost/issues)

Start with TestConcurrentZip in pkg/cli/zip_test.go and its expected output in pkg/cli/testdata/zip/testzip_concurrent. Reproduce the focused test and inspect the concurrent log output around heap profile writing and sensitive-settings warnings. Done means the test passes reliably with the expected output.
